This proposed AD was prompted by inspection of RR Trent 800 engines returned from service that revealed flame erosion and axial cracking on the aft face of the stage 3 disk rim of the high-pressure compressor (HPC) stage 1-4 rotor disks shaft. This proposed AD would require machining the HPC stage 3 inner shroud, inspecting the HPC stage 1-4 rotor disks shaft, and replacing the HPC stage 1-4 rotor disks shaft if found defective. We are proposing this AD to prevent uncontained failure of the HPC stage 1-4 rotor disks shaft, damage to the engine, and damage to the airplane.", "2016-07-26", 2016, 7, "https://www.federalregister.gov/documents/2016/07/26/2016-17160/airworthiness-directives-rolls-royce-plc-turbofan-engines", "https://www.govinfo.gov/content/pkg/FR-2016-07-26/pdf/2016-17160.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211- Trent 892B-17, and RB211-Trent 895-17 turbofan engines...", null]], "columns": ["document_number", "title", "type", "abstract", "publication_date", "pub_year", "pub_month", "html_url", "pdf_url", "agency_names", "agency_ids", "excerpts", "regulation_id_numbers"], "primary_keys": ["document_number"], "primary_key_values": ["2016-17160"], "units": {}, "query_ms": 108.9392090216279, "source": "Federal Register API & Regulations.gov API", "source_url": "https://www.federalregister.gov/developers/api/v1", "license": "Public Domain (U.S. Government data)", "license_url": "https://www.regulations.gov/faq"}
